I made the dress using a leotard pattern, just adding the skirt. Due to the sheerness of the white spandex, I had to use 2 layers of it, plus a layer of nude spandex.
I made the boot covers and sewed them onto a pair of tights, and made the cape out of white stretch spandex. The fur collar piece I made out of faux fur, stuffed with batting for some fluff.
The gloves I bought, the collar and belt I made.

In 2012 I changed it up and wore a white corset I had with it, to do the more traditional look. all of the accessories were the same.
